To all whom it may concern.-

Be it known that I, J osnrn ScHNE1BLE,' a citizen of the United States,residing in Weehawken, in the county of Hudson, in the State of. NewJersey, have invented certain new and useful Im rovements in Coolers orCondensers, of whic the following is a specification, reference beinghad to the accompa rli fing drawings, forming a part hereof.

invention relates to coolers or condensers of the general type shown inLetters Patent of the United States, No. 710,810,'

, the inner pipes and the returnends. It has been soug t to accomplishthe desired object by providing elastic packing between the ends of thepipes and the bends, the latter bein rigidly secured to the headers; butit is foun in practice that such elasticpackin is quickly cut to piecesand ceases-to accomp 1sh 1ts purpose. It has also been sought to providean expansion-j oint between the end of each inner pipe and thecorresponding end of the returnend; but as such return-bends arefrequently detached in order to permit the cleansing of the interior ofthe inner pipes such expanslonjoint also quickly ceases to accomplishits intended pur ose. In the present case these difliculties ave beencompletely overcome and leakage at these joints wholly prevented evenwhen the apparatus is subjected to extraordinary conditions, such as theimmediate chan e from liquid nearly at the boilingoint to iquid nearlyat the freezing-point, y securing the bends to the headers in a yieldingmanner, so that they shall move with the ends of the inner pipes as thesame expand and contract and providing between the end of each pipe andthe corresponding end of the bend an ordinary packing which maintains atight joint under all conditions and does not suffer in the detachmentand reattachment of the bends.

The invention will be more fully explained hereinafter with reference tothe accompanying drawings, in which it is illustrated.

. ture in or In said drawing,'Figure 1 is a top view of a sufficientportion of sucha cooler 0r condenser as is shown insaid Letters Patent N0. 710,810 to enable'the a plication of'the provement to e: understood.ig. 2 is a v1ew, partly in vertical section, on the plane indicated bythe line 2 2 of Fig. 1 and partly in side elevation. Fig. 3 is a view inend elevation, showing the bend swung away from the ends of-the pipes.

As shownin the construction shown and described in said Letters PatentNo. 710,810, the

present imcooler or condenser is made up of as many sets I of pi es forthe liquid to be cooled and pipes for the rine or ammonia or' otherrefrigerant as nl lafiy be necessary to produce the desired re- S becondensed, or, it might be, the liqui to be heated, if the apparatus beused for such pur pose, 1S prefera y carried in the pi as A, arrangedcentrally within the pipes which conduct the cooling or heating medium.Both the inner pipes and the outer pipes are supported by couplingiecesor headers C,

the pipes B being prefera 1y threaded therein with a tight joint and theipes A, which r0- ject beyond the pipes B, having, preferably, a leadedjoint, as at c',whichw1ll permit expansion and contraction of the pipesA with respect to the cou lin or headers C. Each coupling-piece orTread; C is secured to the coupling-piece above or below it, as by boltsThe liquid to be cooled or the va or-to 0, each coupling-piece or headerbeing chambered, as ate, and communicating with the couplinghabove orbelow it, as the. case may be, so t at acontinuous conductor .is'rovided for the cooling or heatin me mm through the pi es B from one end0% the cooler to the other. he inner pipes A are also connected in(pairs at opposite ends of the strucer to provide a continuous passagefor the liquid or vapor to be heated or cooled from one end of thecooler to the other, and for this purpose bends D are provided, eachbend bemg formed-with seats, as at d, and.

suitable packing to make tight joints with the ends of the correspondingpi es A.

Since it is necessar to provid e ready access to the interior 0 thepipesA to enable them to be cleaned from time to time, the bends D should bereadily detachable from the ends of the pipes A. They must also be heldclosely against the ends of such pipes in order to make tight joints,and provision must be made to accommodate the expan- IIO sion andcontraction of the pipes A,-a'ltho'ugh the bends are 'su ported by thecou lings or headers 0. As ereinbefore stated? it has been pro osed tomake the packing D sulficiently e astic to compensate for the expansionand contraction of the pipes while the bends are held rigidly to thecouplings or headers, and-ithas also been proposed to-permit the bendsto fit over the ends of the pipes, provision being etween the bendsandthe pipes in-or er-to accommodate the expansion and contraction ofthe pipes. Both of these devices, however, have proved unsatisfactor inpractice, because after a comparatively sl iort use they permitleakageat the joints. In the present instance the packing at the joint(1 is of or dinary character and permits-a-tight joint to be maintainedunder all conditions. The bend D, however, is held yieldingly withrespect to the supporting header or coupling, but tightly against theends of the pi es A, so that each bend instead of being rigi ly fixedwith respect to the header or coupling is permitted to move with respectthereto as the pipes A expand or contract. Accordingly springs f areprovided between the thumbnuts f onthe link-bolts F and the slotted lu sd formed on the bends D to receive the lin bolts. The latter may beivoted upon the bolts 0 to ermitthe easy etachment of the bends. T e srin s f are sufiiciently stifi' to ermit the ben s to be held againstthe en s of the pipes A with such pressure as to prevent leakage at thejoints d, and yet they yield'sufficiently to permit the bends toaccommodate themselves to the-expansion and made for expansion-'omtsseaeee contraction of the ipes A without disturbing the oint d. Wiiihthis improvement the leaking of the joints in th'eold constructionsreferred to is Wholly overcome, and the oints d remain tight under allconditions even when the structure is subjected to sudden es oftemperature, so

and excessive chan that the shifting of t e pipes A with respect to theheadersor couplings c is considerable.

I claim as my invention 1. In a coolerorcondenser, the combination of asupport, pipes so mounted -in the support so as to been-gable of endwisemovement therein, a ben connecting one pipe with another and means tohold said "bends detachably against said pipes and yieldingly withrespect to said support whereby said bend may move with theends of saidpipes in their movement relative to the suppora suhstantiall'y asdescribed.

2. In a cooler or condenser,'the combination of a l support, pipessomounted in the support as to be capable of endwise movement therein, adetachable bend connecting the end of one pipe with another, means fordetachably securing said bend to said support against the ends of saidpipes, said means including springs to ermitv the bend to move with theends of said pipes in their movement relative to the support,substantially as described.
